To all whom it may concern.-

Be it known that I, Bnn'ron L. WRIGHT, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented a new and useful Sash-Holder, of which the following is a specification.

My invention has for its object to provide a simple and inexpensive sash-holder adapted for general use, and especially adapted for use where it is desired to lock an upper sash in a slightly-lowered position or alower sash in a slightly-raised position, or both, for purposes of ventilation, that cannot get out of order and will always operate, that may be applied to any window-sash by any person, either skilled or unskilled, without other tools than a screwdriver, will require no cutting or removal of wood from either sash, which will hold a sash, either upper or lower, in any position in which it may be placed by frictional engagement only, and. which when not required for use may be easily thrown to an inoperative position, in which it will remain until required for use.

With these objects in VIEW I have devised the novel automatic friction sash-holder, which I will now describe, referring to the accom' panying drawings, forming part of this specification, and using reference characters to indicate the several parts.

Figure 1 is a rear elevation of my novel sashholder as in use retaining a sash or sashes in an open position, portions of the side rails of upper and lower sashes and the meeting-rail of the lower sash being shown; Fig. 2, a corresponding side elevation, a portion of the side rail of an upper sash appearing in elevation and the meeting-rail of a lower sash appearing in section, the fastener appearing in full lines in the locking position and in dotted lines in the inoperative position; Fig. 3, a rear elevation corresponding with Fig. 1, the sashes being omitted, illustrating {a variant form of the invention, the essential parts, however, remaining the same; and Fig. 4 is a side elevation corresponding with Fig. 3.

My novel sash-fastener consists, essentially, of a body adapted :for attachment to the top of the side rail of a lower sash and provided with an incline and a holding-roller adapted to engage the incline and the side rail of an upper sash and carried by an arm which swings on an oscillating fulcrum-pin, the pivot-pin of the roller being in a horizontal plane slightly above the plane of the fulcrum-pin when in the operative position.

10 denotes the body, which may be formed from a single piece of sheet metal with duplicate side pieces, as in Figs. 1 and 2, or may be cast in a single piece, as in Figs. 3 and 4. The base 11 is in either instance provided with holes 12 to receive screws, by which the fastener is attached in place upon a window-sash, and with an incline 13.

1 1 denotes the holding-roller, which is carried by a swinging arm 15in the present instance a double arm the sides of which are connected by a cross-piece 25. The essential feature of this arm is that the fulcrum-pin 16, on which it oscillates and by which it is connected to the body, is movable. In Figs. 1 and 2 the body is provided with side pieces 17, each of which is provided with a curved slot 18, said slots being engaged by the ends of the fulcrum-pin, as clearly shown. The rear end of the swinging arm is preferably provided with a finger-piece 19 for convenience in manipulating the fastener. The fulcrum-pin in this form may be rigidly secured to the arm. It will be noted that in the form illustrated in Figs. 1 and 2 the position of the fulcrum-pin when at the rear ends of the slots relative to the position of the holding-roller on the incline renders it impossible for the pivot-pin of the roller to drop below the horizontal plane of the fulcrum-pin. In the form illustrated in Figs. 3 and 1 the same result is accomplished by the engagement of the cross-picce on the link with the hub on the base. W'hen desired. the fastener may be thrown out of operative position by tilting the arm upward to the position shown in dotted lines in Fig. 2, cross-piece 25 engaging the body and acting to retain the arm against further backward movement. The same result is accomplished in the other form by the engagement of the finger-piece with cross-piece 24 on the link.

In the form illustrated in Figs. 3 and 41 the body is shown as provided with a central web 20, which is straddled by the arm, shown as made double, as in the other form. The fulcrum-pin in this form is pivoted to a link 21, which is itself pivoted to a hub 23 on the body, as at 22. The link is shown as provided with a cross-piece 2 1, which is adapted to en gage hub 28 to limit the backward movement of the link.

The operation will be readily understood from the drawings. In raising or lowering a sash the operator places a finger on the finger-piece 19 and tilts the arm sulliciently to place the holding-roller out of engagement with the side rail of the upper sash. He then after adjusting the sash or sashes allows the arm and holding-roller to swing into operative position, as in Fig. 2, the fulcrum-pin moving backward and bearing against the rear ends of slots 19 in the form illustrated in Figs. 1 and 2 and the link tilting backward until stopped in the form illustrated in Figs. 3 3411614:- In this position of the parts both sashes may be retained in any position in which they are placed. As the pivot-pin of the holding-roller is in a plane slightly above the fulcrum-pin of the arm, it is obvious that it will be impossible to raise the lower sash or to lower the upper sash without manipulation of the fastener, which cannot be done from the outside. This fastener is especially adapted for use where it is required to lower an upper sash or to raise a lower sash a short distance for pur poses of ventilation, leaving both sashes free to be moved toward the closing position at any time, if desired, but rigidly locking them against movement toward the open position. The fastener may be readily disengaged at any time, however, by a slight downward movement of the lower sash if raised or a slight upward movement of the upper sash, either of which will cause the holding-roller to travel upward on the incline and disengage the sashes. By providing a sliding fulcrum for the swinging arm I insure that there will be under no circumstances the slightest danger of the roller wedging between the incline and the side rail of the upper sash no matter how loose the sashes may be, as the fulcrum-pin will readily move forward in either form when either sash is moved toward the closing position, thus relieving the friction of the holding-roller on the incline and the side rail of the upper sash.

Having thus described my invention, 1 claim 1. A sash-holder comprising essentially a body having an incline, a holding-roller adapted to travel on the incline and a swinging arm by which the roller is carried and which is connected to the body by means of a movable fulcrum.

2. A sash-holder consisting of a body having an incline and side pieces provided with curved slots, a holding-roller adapted to travel on the incline and a swinging arm by which the roller is carried and which is provided with a fulcrum-pin engaging the slots.

3. A sash-holder consisting of a body having an incline, a holding-roller adapted to travel on the incline, a swinging arm by which the roller is carried and which is provided with a fulcrum-pin having a sliding engagement with the body and means for retaining the pivot-pin of the roller slightly above the horizontal plane of the fulcrum-pin when the roller is in operative position.

4:. A sash-holder comprising a body having an incline, a holding-roller adapted to travel on the incline, a swinging arm by which the roller is carried and which is connected to the body by means of a movable fulcrum and means for, retaining the arm and roller out of operative position.

5. A sash-holder comprising a body having an incline, a holding-roller adapted to travel on the incline, and a swinging arm by which the roller is carried and which is provided with a fulcrum-pin which engages the body with asliding movement and with across-piece adapted to engagethe body to retain the arm and roller in an inoperative position.

In testimony whereof I affix my signature in presence of two witnesses.
